Passage
Thou shalt fear Jehovah thy God, and serve him, and shalt swear by his name.
Thou shalt fear Jehovah thy God, and serve him, and shalt swear by his name.
Deuteronomy 6:11 and houses full of everything good which thou filledst not, and wells digged which thou diggedst not, vineyards and oliveyards which thou plantedst not, and thou shalt have eaten and shalt be full;
Deuteronomy 6:12 [then] beware lest thou forget Jehovah who brought thee forth out of the land of Egypt, out of the house of bondage.
Deuteronomy 6:13 Thou shalt fear Jehovah thy God, and serve him, and shalt swear by his name.
Deuteronomy 6:14 Ye shall not go after other gods, of the gods of the peoples that are round about you;
Deuteronomy 6:15 for Jehovah thy God is a jealous God in thy midst; lest the anger of Jehovah thy God be kindled against thee, and he destroy thee from the face of the earth.
The verse centers on "thou", "shalt", "fear", "jehovah", "serve", "swear", and "name". It is saying that the verse draws attention to "thou" and "shalt", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 12's "then beware lest thou forget Jehovah who..." into verse 14's "Ye shall not go after other gods...", so "thou" and "shalt" belong inside that flow. In Deuteronomy context, the local focus is covenant, worship, and faithfulness.
A plain takeaway is to answer the verse's own emphasis on "thou" and "shalt" with trust shaped by these words, not by a vague optimism outside the passage.
